DETAILED DESCRIPTION

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the invention. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the invention as recited in the appended claims.
At present, many terminals, particularly intelligent terminals, are provided with touch screens. A user may complete operations through various touch operations on a touch screen, for example, an application may be started by a click operation on the touch screen. It brings great convenience to a user. However, it may lead to accidental operations, bringing the user with some unnecessary troubles.
For solving this problem, the present disclosure provides a method for preventing an accidental touch of a terminal with a touch screen. The method is applicable to a terminal with a touch screen, and an execution entity corresponding to the method may be a terminal carried by a user. As shown in FIG. 1, the method includes Steps 101-103.
Step 101: detecting current status information of the terminal, and acquiring a current touch gesture which is acquired by a module configured to acquire a touch gesture, wherein the current status information of the terminal includes any one or more of posture information and motion status information of the terminal.
The posture information of the terminal may be information such as an inclination angle of a body of the terminal, and the posture information of the terminal may be acquired by a gyroscope.
The motion status information of the terminal may be displacement information of the terminal, acceleration information of the terminal, or a combination thereof. The module configured to acquire the touch gesture may be a touch screen or touch key which acquires the current touch gesture on the basis of capacitance detection, or a fingerprint module with a touch function.
Step 102: determining, according to a matching relationship pre-established for a touch behavior, whether the current status information of the terminal and the current touch gesture correspond to the same touch behavior, wherein the pre-established matching relationship is a relationship between status information of the terminal and motion status information of a touch gesture.
By Step 102, it may be determined whether the current touch gesture is effective, and whether the current touch gesture is an intended touch on the touch screen instead of an accidental touch. Specifically, when the current status information of the terminal and the current touch gesture correspond to the same touch behavior, it indicates that the current touch gesture is effective and the current touch gesture is an intended touch of a user on the touch screen instead of an accidental touch. On the contrary, when the current status information of the terminal and the current touch gesture do not correspond to the same touch behavior, it indicates that the current touch gesture is ineffective and should be an accidental touch, for example, it may be a gesture generated by an accidental touch on the touch screen due to unlocking of the screen when the user carries the terminal.
In addition, since the current status information of the terminal is generated by a touch gesture, a motion change may not be obvious. In order to avoid the phenomenon that the detected current status information of the terminal is not so accurate, a chip is additionally arranged in the terminal, the chip may be triggered by the touch gesture on the touch screen to move, and current status information of the chip may be deemed as the current status information of the terminal. Similarly, a matching relationship, pre-established for a touch behavior, between status information of the terminal and motion status information of a touch gesture may also be a matching relationship, pre-established for the touch behavior, between status information of the chip and motion status information of the touch gesture.
Moreover, the preset chip may be a chip where an acceleration sensor is located, the acceleration sensor may detect the status information of the chip where it is located. The chip is arranged below the touch screen in the terminal, and may move after receiving the touch gesture, thereby generating the current status information.
Step 103: when the current status information of the terminal and the current touch gesture correspond to the same touch behavior, executing an operation corresponding to the touch behavior.
When the detected current status information of the terminal and the current touch gesture do not correspond to the same touch behavior, it may be determined that there is an accidental touch, and a protection operation will be carried out. The determination may also be repeatedly for one or more times to recheck whether there is indeed an accidental touch, and a protection operation will be carried out when it is indeed an accidental touch. The protection operation may be locking the touch screen of the terminal, or forbidding starting of a preset program in the terminal within a preset time (for example, forbidding an outbound call, forbidding running of instant messaging software and forbidding running of a shopping application program) or controlling the terminal to enter a low-power-consumption mode, and the protection operation may further prevent the terminal from executing another accidental operation and improve an accidental touch prevention effect.
When the detected current status information of the terminal and the current touch gesture correspond to the same touch behavior, it indicates that the current touch gesture is effective, the probability that the current touch gesture is an accidental touch may be eliminated, and the operation corresponding to the touch behavior may be executed, thereby timely responding to the touch gesture of the user and ensuring good user experiences.
In addition, when the operation corresponding to the touch behavior is executed, the operation may be executed on the local terminal, and information about the touch behavior may also be sent to another terminal connected with the local terminal and the operation corresponding to the touch behavior is executed by the other terminal. For example, if the operation corresponding to the touch behavior is photographing with a photographing application program, the photographing application program may be started on the local terminal for photographing, or the information about the touch behavior may be sent to the other terminal connected with the local terminal and then the photographing application program is started on the other terminal for photographing.
In one embodiment, Step 102, as shown in FIG. 2, may be executed by:
Step A1: determining whether a time difference between a first time when the current status information of the terminal is detected and a second time when the current touch gesture is acquired is equal to or smaller than a preset time difference; and
Step A2: when the time difference is equal to or smaller than the preset time difference, determining whether the current status information of the terminal and the current touch gesture correspond to the same touch behavior.
Due to the reasons of software and hardware, the first time and the second time may be different when a detection module detects the current status information of the terminal and the module configured to acquire the touch gesture acquires the current touch gesture. For preventing inaccuracy of a determination result about whether the current status information and the current touch gesture correspond to the same touch behavior, it is better not to determine whether the current status information of the terminal and the current touch gesture correspond to the touch behavior when the first time and the second time are acquired or only when the first time and the second time are the same. Instead, it may be determined whether the time difference between the first time and the second time is smaller than the preset time difference, and then it may be determined whether the current status information of the terminal and the current touch gesture correspond to the same touch behavior when the time difference is smaller than the preset time difference. In such a manner, the phenomenon that the determination result about whether the current status information and the current touch gesture correspond to the same touch behavior is ineffective because the time difference between the first time and the second time is excessively great may be prevented, and the phenomenon that the current status information of the terminal and the current touch gesture are incorrectly determined to be not corresponding to the same touch behavior because the first time is different from the second time for reasons of the software and the hardware may also be avoided.
In one embodiment, in the matching relationship, the motion status information of the terminal comprises at least one of: displacement information of the terminal, and acceleration information of the terminal, and the motion status information of the touch gesture comprises at least one of: displacement information of the touch gesture, and acceleration information of the touch gesture.
The motion status information of the terminal includes the displacement information of the terminal, such as a displacement direction and a displacement magnitude, and may further include the acceleration information, such as an acceleration direction and an acceleration magnitude, wherein the acceleration information may be determined by an acceleration sensor module or a gyroscope. Similarly, the motion status information of the touch gesture may include at least one of: the displacement information about displacement of the touch gesture on the touch screen, such as a displacement direction and a displacement magnitude, and sliding acceleration information, such as an acceleration direction and magnitude.
In one embodiment, Step 102, as shown in FIG. 3, may be executed by the following steps.
Step B1: acquiring motion status information of a touch gesture corresponding to a preset touch behavior on the touch screen, and status information of the terminal generated under the action of the touch gesture.
Step B2: establishing the matching relationship according to the acquired motion status information of the touch gesture corresponding to the preset touch behavior on the touch screen and the acquired status information of the terminal generated under the action of the touch gesture.
Each touch behavior corresponds to a touch gesture, and the touch gesture may not only have certain motion status information (i.e. the displacement magnitude and direction and acceleration magnitude and direction of a motion of the touch gesture relative to the touch screen when the user performs touch operation on the touch screen to generate the touch gesture) on the touch screen of the terminal, the terminal may also generate status information (i.e. an angle and displacement magnitude and direction and acceleration magnitude and direction of a motion of the terminal relative to a still reference such as the ground and a desktop) relative to the still reference such as the ground and the desktop, and the two motions correspond to each other, so that the matching relationship may be accurately established after the motion status information of the touch gesture corresponding to the preset touch behavior on the touch screen and the status information of the terminal generated under the action of the touch gesture are acquired.
Step B3: determining motion status information of the touch gesture corresponding to the current status information of the terminal according to the matching relationship.
After the current status information of the terminal is detected, the motion status information of the touch gesture corresponding to the current status information may be accurately according to the matching relationship.
Alternatively, status information of the terminal corresponding to the current motion status information of the touch gesture may also be determined according to the matching relationship.
Step B4: determining whether the motion status information of the touch gesture corresponding to the current status information of the terminal is matched with the motion status information of the current touch gesture.
Alternatively, it may also be determined whether the status information of the terminal corresponding to the current motion status information of the touch gesture is matched with the current status information of the terminal.
Step B5: determining that the current status information of the terminal and the current touch gesture correspond to the same touch behavior when it is matched.
Whether the current status information and the current touch gesture correspond to the same touch behavior may be accurately determined according to whether the motion status information of the touch gesture corresponding to the current status information of the terminal is matched with the acquired actual motion status information of the current touch gesture. Specifically, when the motion status information is matched with the actual motion status information, it indicates that the current touch gesture is the touch gesture corresponding to the current status information of the terminal, and it further indicates that the current touch gesture is effective and the current touch gesture and the current status information of the terminal correspond to the same touch behavior.
In one embodiment, the pre-established status information of the terminal corresponding to the same touch behavior may include: an acceleration variable of the terminal in one direction is equal to or more than a first preset variable; or the acceleration variable of the terminal in one direction is equal to or more than a second preset variable and (an) acceleration variable(s) in another direction or multiple other directions is/are equal to or smaller than a third preset variable. In the matching relationship, one direction is matched with a sliding gesture of the corresponding touch gesture, and for example, when the sliding gesture of the corresponding touch gesture is sliding in a direction A, an acceleration variable of the terminal in the direction A is required to be equal to or more than a variable, or an acceleration variable in a direction perpendicular to a horizontal plane where the touch screen is required to be equal to or more than a variable. In one embodiment, one direction may be the direction perpendicular to the horizontal plane where the touch screen is located, or a direction parallel to the horizontal plane where the touch screen is located. One direction may be the direction perpendicular to the horizontal plane where the touch screen is located, for example, an upward or downward direction perpendicular to the horizontal plane, or the direction parallel to the horizontal plane where the touch screen is located, for example, an upward, downward, leftward or rightward direction parallel to the horizontal plane.
For example, when the touch behavior is a screen unlocking behavior, the touch gesture corresponding to the screen unlocking behavior is vertical and downward double-click on the touch screen, motion status information of the vertical and downward double-click gesture includes a downward direction and acceleration magnitude of a millimeters/second of continuous two accelerations within a set time period. Correspondingly, status information, which is generated under the action of the vertical and downward double-click gesture, of the terminal includes a downward direction and acceleration magnitude of b millimeters/second of continuous two accelerations within the set time period; and a matching relationship may thus be established, and in the matching relationship: the motion status information of the vertical and downward double-click gesture includes the downward direction and acceleration magnitude of a millimeters/second of the continuous two accelerations within the set time period, and the status information of the terminal includes the downward direction and acceleration magnitude of b millimeters/second of the continuous two accelerations within the set time period.
Corresponding to the abovementioned embodiment, in one embodiment, when the current status information of the terminal includes current displacement information of the terminal, Step 102, as shown in FIG. 4, may be executed by:
Step C1: determining current acceleration information of the terminal according to the current displacement information of the terminal; and
Step C2: determining whether the current status information and the current touch gesture correspond to the same touch behavior according to the current acceleration information of the terminal and the matching relationship.
The acceleration information may reflect a motion status of the terminal most directly. Therefore, when the status information is the displacement information of the terminal, the current acceleration information of the terminal may be determined according to the displacement information, and then it may be determined whether the current status information of the terminal and the current touch gesture correspond to the same touch behavior according to the current acceleration information and the pre-established matching relationship.
In another embodiment, when the terminal is handheld by the user, at least one finger of the user may touch the touch screen under a normal condition, and the body of the terminal may form a certain inclination angle with the horizontal plane. At this time, a matching relationship may be established according to experimental data, and in the matching relationship, the status information of the terminal includes: the inclination angle of the body of the terminal relative to the horizontal plane is within a preset angle range, and correspondingly, the motion status information of the corresponding touch gesture includes that a pressing duration of the touch screen reaches a preset time duration. If the current status information of the terminal and the motion status information of the current touch gesture are matched with the matching relationship, it indicates that the terminal is currently handheld by the user, and if the touch screen subsequently receives a touch gesture, operation may be performed according to the accidental touch prevention method provided by the present disclosure.
